    Nice work and nice blades.

    That looks great. I love the look of the darkened cutting edge!

    Did you neutralize them afterwards? I think a lot of us are using ferric chloride, which you can get from Radio Shack (listed at Etchant Solution). Generally, I use this in a 1:3-4 solution (water:fecl). I find that it is pretty important to neutralize them afterwards to avoid making them more reactive. TSP or ammonia work pretty well for this. Also helps to make sure that the blades are extremely clean before etching them. I generally wipe them with a bit of acetone to make sure I haven't got any of my fingerprints on the blades first.

    industrial gallon size glass jars that our hamburger pickles come in at work, worked really well for me FWIW as far as containers go.

    i actually prefer the look of the vinegar patina, which i may just try to do over the etch.

    i cleaned with soap and scrubbed with fine steel wool prior to etching. only rinsed with cold water in between each dunk plus the scrubbing off the oxidized stuff.
    was told a more diluted solution brings out more contrast.

    how'd you do the vinegar patina? is it like etching but using vinegar as the acid instead?

    Looks great! I haven't tried with that dilute a solution before. -Kinda like a hybrid between the pcb and hot vinegar methods.

    Wouldn't a baking soda/water solution work for this also?

    That's what I use when "aging" nickel hardware.

    processed 50# of root veg today with the watanabe, and don't have a huge callous on my index finger for the first time. it really does do the work for you! never encountered something that glides through carrots and stuff with such ease.

    justin - your etching results from your shig is what convinced me to give this a try, thanks for the inspiration! i really prefer the shades of gray especially with dark near the edge over polished look. and it gets darker where i thinned, almost looks like a shinogi line
